Alright folks, Rusty here. Let's take a look at what Jaconé's got cooking for us over the next couple of weeks.
Right now, there's a bit of a quiet start, but don't let that fool you. We've got a solid run of clean, fun-sized surf on the way, especially through the first week. The water temperature is sitting right around average for this time of year, so no surprises there.
Saturday morning is where it kicks off. Jaconé is showing some nice 5ft swell from the SSW with a 10-second period. The combined energy is moderate at 961, and with glassy conditions thanks to a light 5 km/h wind from the west, it’s going to be clean. Expect good, fun waves to start your weekend.
Sunday sees the swell bumping up to a solid 8ft from the SSW, but the onshore wind is going to spoil it. That's one to skip unless you're desperate for a paddle. The combined energy jumps to a strong 1646, but it'll be messy.
Monday morning is the real standout for me. We’ve got 6ft of S swell with a 10-second period, and the wind is a glassy 5 km/h from the ENE. The combined energy is 933—moderate but punchy. This is going to be clean, offshore-quality surf with good shape. Get out there early.
Tuesday morning keeps the good vibes going. The swell drops a touch to 5ft from the SSE, but with glassy 5 km/h wind from the north and combined energy at 683, it’s perfect for a longboard or a summer groveler. Clean, light, and fun.
Wednesday and Thursday mornings both offer glassy conditions again, with 5ft SSW swell and light winds. The energy stays moderate, and the waves will be clean but not epic. Good for a session if you’re keen.
Now, looking further out to Friday the 10th and Saturday the 11th, the swell drops off. Friday morning has clean 4ft SSW swell with light offshore wind, but the energy is low at 330. After that, it gets small and wind-affected. Expect a bit of a lull through the middle of the second week.
Things start to look interesting again around Wednesday the 15th. The swell picks back up to 4ft from the SSW with clean offshore wind, and the energy returns to 368. Then by Thursday the 16th it’s pushing 5ft, but the wind goes onshore.
Here’s the big news for the brave: Friday the 18th and Saturday the 19th bring some serious size. Swells hit 8ft to 10ft from the SSW, with long periods of 14-15 seconds. The combined energy shoots up to 3791 on Saturday morning. That is a lot of power. However, the wind is cross-shore and it’s predicted to be too big for this break, making it a real challenge and only suitable for experienced surfers with a death wish and a big wave gun. The very long period (15 seconds) means it'll be grinding, but at a beach break setup like Jaconé, it might not be the cleanest.
The best bet: Lock in Monday morning the 6th for the best combination of size, clean conditions, and moderate energy. Tuesday morning the 7th is a very close second for clean, smaller waves.
Stay stoked, and I'll catch you in the water.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
